渐近状态

In terms of linear matrix inequalities, a sufficient condition for the solvability of the problem is given.

运用线性矩阵不等式，设计了状态反馈控制器，使得闭环系统对于允许的不确定性，总是渐近稳定的。

In this model, we discuss the effect of tax policy on economic growth on the condition of market competitive equilibrium. Two chief conclusions are drawn: firstly, when the government has carried out steady tax policies, for consumers there exists unique optimal capital stock path along which economy can grow sostenuto and steadily; when the tax path given by the government converge to some constant tax rate, there still exists one capital stock path which can make the whole economy grow gradually and converge evenly to the optimal state.

在该模型中，我们讨论了在市场均衡条件下，税收政策对经济增长的影响，得到两个主要结论：一、当政府实行稳定的税收政策时，消费者存在着唯一的最优资本存量路径，沿着此路径经济能够持续平稳并且最优地增长；当政府给定的税收路径不稳定但能收敛到某个常值税收率时，此时也存在一条资本存量路径，它能使整个经济渐近平稳地增长，并且最终收敛到最优状态。

Be based on these conditions, construction gives strict linear matrix inequality , filling property proved the Schur that uses matrix next to be below the condition of linear matrix inequality, system of earning closed circuit is asymptotic stability, specific condition feedback gave out to control a law in the meantime.

基于这些条件，构造出严格的线性矩阵不等式，然后利用矩阵的Schur补性质论证了在线性矩阵不等式的条件下，所得闭环系统是渐近稳定的，同时给出了具体的状态反馈控制律。

That is to say that, the original signal of the closedloop system asymptotically converges to zero, while all the other signal of the closedloop system are uniformly bounded.

即闭环系统的原始状态是渐近收敛于零的，而其他所有的信号是一致有界稳定的。

It stably subsided after its formation. During Palaeogene ang Neogene salt-forming, Kuqa basin experienced strong-weak-strong tectonic stages, and its center of subsidence moved gradually from north to south and depocenter from northwest to east and southeast. Because of tectonic differentiation, series of second depression formed in Kuqa basin.

盆地自形成以来一直处于稳定的沉降状态，在古近纪和新近纪成盐期，盆地经历了强-弱-强3个构造演化阶段，其沉降中心由北而南逐渐迁移，沉积中心由北西逐渐向东、南东方向迁移，盆地内的构造分异渐趋明显，形成了一系列次级凹陷。

When a matrix inequality is satisfied, based on the modified Lyapunov function, the system without unknown disturbance can be quadratically stabilized under static state feedback control.

然后研究离散时间时延系统的鲁棒跟踪控制问题，通过求解一个LMI得到控制器的增益矩阵，进而使得闭环系统的状态变量渐近跟踪上任意预先设定的轨迹。

Researching and developing riderless bicycle is a important work offering scientific and actual significance . Internal and overseas research actuality was summarized in this paper , existent problems was analyzed , and then primary development direction of riderless bicycles was presented .

而自行车机器人实际上就是一种无人驾驶的自行车，因此，自行车机器人的控制问题相当困难，如不能采用连续或可微的纯状态反馈实现系统的渐近稳定，不能采用非线性变换实现整体线性化等。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
